when i run "supervisorctl status hitbot" then i face this error
FATAL Exited too quickly (process log may have details)
#/bin/gunicorn_start
Here **BIND= ip_address:port **
/etc/supervisor/conf.d/hitbot.conf
But when i type these command
In log file
But when it test gunicorn_start by "bash /bin/gunicorn_start"* then it working fine
Try this command: pkill -HUP gunicorn
Gunicorn docs: http://docs.gunicorn.org/en/stable/faq.html
"You can gracefully reload by sending HUP signal to gunicorn: $ kill -HUP masterpid"
or with the full command line:
pkill -HUP -f '/usr/bin/python /usr/bin/gunicorn -w 5 -b 127.0.0.1:5000 myapp:app'

I have a Docker container running Supervisor with 2 processes:
Celery
Django
I want Supervisor to exit when one of these processes returns an error.
This is my configuration:
[supervisord]
nodaemon=true
loglevel=debug
logfile=/app/supervisord.log
pidfile=/var/run/supervisord.pid
childlogdir=/app
[program:django]
command=python manage.py runserver 0.0.0.0:8000
redirect_stderr=true
stdout_logfile=/dev/fd/1
stdout_logfile_maxbytes=0
[program:celery]
command=celery -A myapp worker --beat --scheduler django --loglevel=debug
redirect_stderr=true
stdout_logfile=/dev/fd/1
stdout_logfile_maxbytes=0
[eventlistener:processes]
command=bash -c "printf 'SUPERVISORD READY' && while read line; do kill -SIGQUIT $PPID; done < /dev/stdin"
events=PROCESS_STATE_STOPPED,PROCESS_STATE_EXITED,PROCESS_STATE_FATAL
When I have a fatal error that should normally make Docker exit, Supervisor tries to launch Django again and again.. while the goal is to exit.
What's missing here?
I tried different other configurations but it's not working.
As documented [autorestart]
Default: unexpected
If unexpected, the process will be restarted when the program exits
with an exit code that is not one of the exit codes associated with
this process’ configuration (see exitcodes)
I have a shell script called kill.sh that helps me restart a python script I've written. I normally use pkill -f main.py to kill my forever-running python script. However, when I wrote it into a shell script it does not work.
My script
pkill -f main.py
ps aux | grep main.py # Still shows the process running.
While just executing pkill -f main.py in bash command line works as expected. Why is this?
This is not a satisfactory answer, as I cannot find out the root cause of why pkill -f does not work in a script. I ended up using a systemd Service file to manage my python process. Here's an example fyi.
[Unit]
Description=Service Name
[Service]
Environment=PYTHONUNBUFFERED=1
ExecStart=/path/to/python /path/to/python/script.py
Restart=on-failure
RestartSec=5s
WorkingDirectory=/python/project/dir/
Name the file main.service and place it in /lib/systemd/system/
Running the service systemctl start main.service
Stop the service systemctl stop main.service
Restart the service systemctl restart main.service
Show status and output systemctl status main.service -l
Now I don't have to worry about multiple processes running. If the program dies it'll even restart.
I am running a bash script as systemd service but it is giving me this error
Failed at step EXEC spawning /home/pipeline/entity-extraction/start_consumer.sh: Permission denied

My bash scrip is running 2 Python scripts and it runs fine when I run it from terminal as

echo "new_pid:$new_pid"
# Here I want to kill FIRST Consumer.py
echo "killing first consumer"
kill "$pid"
sleep 60
# Here I want to kill SECOND Consumer.py
echo "killing second consumer"
kill "$new_pid"
done

[Unit]

how can I resolve this issue ?
You have to set the shebang line and permission to the script, for systemd to execute.
Add #!/bin/bash to the start of the bash script. And do the following,
chmod 755 /home/pipeline/entity-extraction/start_consumer.sh
I am very new to fabric. In my fabric file I want to restart gunicorn. For that I am killing the gunicorn process first and then starting it..
It looks like:
def restart_gunicorn():
run('ps ax|grep gunicorn')
run('pkill gunicorn')
run('gunicorn -b 0.0.0.0:8080 %(path)s/application/wsgi &' % env)
When I run this it gives me error at pkill gunicorn because at start i will not have any gunicorn process running. So I want to have a check lik if gunicorn processes are running then only kill gunicorn. If not gunicorn process are running I just want to start the gunicorn process..
How can I do this ?
Need help. Thank you
You can just add settings(warn_only=True) and will only give you a warning, but the execution won't fail:
def restart_gunicorn():
run('ps ax|grep gunicorn')
with settings(warn_only=True):
run('pkill gunicorn')
run('gunicorn -b 0.0.0.0:8080 %(path)s/application/wsgi &' % env)
More info on settings context manager here: http://docs.fabfile.org/en/1.10/api/core/context_managers.html#fabric.context_managers.settings
docker container exited immediately after python script execution:
docker run -t -i -v /root/test.py:/test.py zookeeper python test.py
(test.py starts zookeeper service )
The command is successful but exits immediately with out starting container. I could NOT start the container with "docker start container id".
Manually running "python test.py" is successful inside container but not during "docker run ...."
Just starting the server is not enough. When the CMD exits, so does the container. Thus, if you start a service that's a daemon, you need to keep your process alive. This can be achieved by, for example, tailing the service log file. supervisord is another way to run processes and keep the CMD alive.
For example, you might do
CMD /test.py && tail -F /var/log/zookeeper.log
Running from the commandline you could do something similar
docker run -t -i -v /root/test.py:/test.py zookeeper bash -c "python test.py && tail -F /var/log/zookeeper.log"
